I’ll level with you, FanGraphs reader: I can’t imagine that FanGraphs analysis is exactly what you’re most interested in right now, baseball-wise. The exciting things going on are the games on the field as they happen. These playoff races are amazing. The schedule sets up with a wonderful mix of both-teams-in games and rivals playing spoiler. In that context, I can’t imagine that many people are dying to read about Tommy Kahnle’s changeup-heavy arsenal, just to pick on a random article I recently wrote.

That’s never stopped me from writing about whatever random thing caught my eye, but I thought I’d take advantage of a slow week (again, just in my kind of baseball analysis, not in actual baseball) to go over some predictions I made before the season. I like to look back on my own work for a few reasons — not just to bask in successes, but that’s certainly part of it. It’s also useful to talk process and separate bad outcomes from bad ex-ante decisions, though to be honest, that’s really hard, so I’m not certain I’ll get it right today.

I’ve named the column after one of my favorite weird sports things. I always knew this, but I’ve noticed it more since I started playing in a recreational softball league. After you return to the dugout, there’s a pretty good chance someone will slap your butt with their glove. It doesn’t matter what you did, there’s always a reason to. Did you score a run or make a great defensive play? It often comes with an “attaboy” or “way to go.” Did you make an out or embarrass yourself in the field? “Get ‘em next time” is nearly guaranteed. The butt slap? That’s a constant. The words that go with it? They’re versatile. Without further ado, let’s figure out whether my hypothetical dugout should be congratulating or consoling me.

Last year, I looked into the odds displayed on Apple TV+’s Friday Night Baseball broadcasts. I found them to not be very good. Then I stopped paying attention; there are a ton of baseball games on every week, most of which Apple does not broadcast, and even when I did watch an Apple game, I basically ignored the odds. I knew they were silly, after all – why distract myself by looking at them?

Of course, I didn’t really expect that to keep going indefinitely. Apple is a massive company. They have more than 150,000 full-time employees, and a ridiculous proportion of that group knows how to code. At its core, this is a data problem. There are companies I’d trust over Apple to solve a data problem, but there aren’t a lot of companies, you know? Sure, they outsourced their predictions to nVenue, a sports analytics company, but they’re Apple. Surely they’d find a way to make this all work. I noted their relative inaccuracy in my head as a temporary curiosity and moved on.

Last month, I started compiling data for an update. It’s all well and good to assume things have changed, but at some point, you have to go verify it. I decided to wait for the back half of the season because of the way I designed my test, which I’ll now explain. Similar to last time, I started by watching a bunch of games. This time, I got data from the 12 Apple TV+ games played between August 18 and September 22. I watched the entirety of those broadcasts and noted the last probability, if any, displayed before every pitch. Read the rest of this entry »

After a week off to recharge my batteries — and watch other sports, gasp — it’s time for another installment of five things that caught my eye in baseball this week. Honestly, this list is almost superfluous at this time of year. The standings are so jammed together that half the games in baseball have playoff implications. Teams are getting hot at the right time or collapsing down the stretch in equal measure. Still, you can’t watch everything, so here are some delightful moments you might have missed.

1. Legends, in the Fall
It’s been a rough year for Adam Wainwright. He has put up by far the worst season of his career — a 7.40 ERA says all you really need to know about it — and the Cardinals have collapsed from the perpetual contention he enjoyed for the vast majority of his career. They’ve seemingly played more meaningless games this year than in Wainwright’s entire previous time with the club. Read the rest of this entry »

They say everything in baseball happens in cycles. Actually, I’m not sure if they say that, but it certainly sounds like a real quote. And that’s fortunate for me, because today I’d like to talk about another thing that happens in cycles: Tommy Kahnle being a valuable reliever. Years after it seemed like that might never happen again, he’s back on the Yankees and pitching well, to the tune of a 2.66 ERA and 3.97 FIP across 40.2 innings of work, that despite a four-walk disaster of an outing on Wednesday night.

The last time Kahnle was good and healthy was also with the Yankees, in 2019. Before that, you’d have to go back to 2017 (split between the White Sox and Yankees). He was hurt and ineffective in 2018, then only pitched a combined 13.2 innings from 2020 to ’22 due to injury. But now here he is, back at it, though you might not know it thanks to the Yankees’ general desultoriness (probably not a word, but my spellcheck didn’t flag it, so let’s roll with it).

The Orioles have a tight grip on the AL East race. With time running out on the season, they have a 2.5 game lead on the Rays with the tiebreaker in hand; the division title comes with homefield advantage throughout the AL playoffs. Their +127 run differential is the third-best in the AL. So then why oh why do we at FanGraphs think they only have a 5.5% chance of winning the World Series, worse than the Astros and Rays and just ahead of the Blue Jays and Mariners?

It’s happened two years in a row now. FanGraphs keeps doubting the Orioles, and they keep winning. But don’t you worry, disgruntled O’s fans. As the resident Orioles believer – I picked them to win their division before the season, even if that was mostly a statement that they were underrated rather than a sincere belief that they were the best team in the East – I’m here to dig through the madness and see what’s going on.

First things first, in these “why don’t the odds believe in my team?” articles, it’s always good to walk through how the odds work. They’re quite straightforward, though straightforward isn’t the same thing as simple. We start at the player level, averaging the Steamer and ZiPS projections to come up with projections for every player in baseball. Then we manually build a depth chart for each team. From there, we stitch those pieces together to come up with team-level offensive, defensive, and pitching projections. We plug those into the BaseRuns formula and get projections of how many runs per game each team will score and allow, then convert those to expected winning percentages using Pythagenpat expectation.

Last week, David Laurila asked me an interesting question. He’d been talking baseball with some baseball players – it’s true, we really do have great jobs – and the conversation landed on Josh Hader. That got Laurila thinking about Hader’s similarities to Spencer Strider. The crux of the discussion: Would Hader have ended up as a lefty version of Strider if, after appearing in the major leagues as a reliever, he’d transitioned back to the starting role he held in the minors?

I love questions like this. They’re fun to research, and I also feel no pressure to reach a definitive answer. Would Hader have ended up as a great starter? It’s clearly unknowable. That gives me a lot more latitude to speculate. In addition, this question isn’t just about Hader. It’s about whether future pitchers with Hader-esque profiles make more sense as starters or in the bullpen. No wrong answers and broad implications? Sign me up.

First things first, let’s talk about what it means to look like Strider as a starter. Strider has two standout pitches, but it’s really one standout pitch and a capable understudy. His fastball explodes through the top of the zone and screws hitters into the ground. It’s not so much the velocity – though that doesn’t hurt – but the shape and release point that combine to bamboozle opposing hitters. Read the rest of this entry »

This all started because I wanted to write about Isaac Paredes. He’s my kind of player, excellent despite all sorts of warning signs that what he’s doing shouldn’t be working. Advanced metrics and in-person scouting assessments are both quite negative on Paredes, and yet he’s batting .255/.354/.503, good for a 140 wRC+, in mid-September. He’s been one of the most valuable players on one of the best teams in baseball. It’s so weird!

But lo and behold, the exact thing I wanted to write about has already been written. Curse you, Esteban Rivera! Well, not actually, of course. Esteban’s writing is great, and it’s also of particular interest to me because he’s so observant of hitting mechanics. But I can’t exactly write an article about how Paredes’ pull-happy tendencies have helped him keep regression at bay when there’s a better article talking about just that already on the site.

All season, the Rangers have been fighting gravity. They stormed out to a lead in the AL West, but they lost Jacob deGrom in the interim. The Astros lurked not far off the pace. But the Rangers persevered and held their lead until the trade deadline. Reinforcements were on the way! Max Scherzer, Jordan Montgomery, Aroldis Chapman — they made more improvements than any other team in the league.

They needed it, too, because Nathan Eovaldi hit the IL the next day. Josh Jung followed not long after. As they slogged through August, the Mariners charged into the AL West race, making it a three-way fracas. No sooner did Eovaldi return than Adolis García succumbed to injury. And now, with the playoffs hanging in the balance and every win at a premium, this:

Right-hander Max Scherzer is expected to miss the remainder of the regular season with a strained teres major — a muscle that connects the scapula to the humerus. Scherzer is, Texas GM Chris Young told reporters, "unlikely" to pitch in the playoffs.

Brutal news for the Rangers.

What rotten luck. For those of you who aren’t anatomists, the teres major is a muscle in the rear shoulder that gets stressed by pitching. It’s been in the news quite a bit this year, in fact. Justin Verlander missed the first month of the season with a low-grade teres major strain. Triston McKenzie missed the first two months of the season with a strained teres major. John Means’ return from Tommy John surgery was delayed by a teres major injury. None of these injuries have seemed to linger, and none required surgery, but the timeline is unfortunately immutable: there’s no chance of Scherzer making it back for the regular season, and little shot of him pitching in the playoffs either.
